Even though the pitch maybe the same, the depth of cut varies according to the nose radius. For the Micro Mini Twin CT type CT03RS-M4,
and CT03RS-M4B the nose radius is 0.03mm, for other types it is 0.05mm. For further details please refer to the standards section.

Precautions when using the MICRO-DEX and MICRO-MINI TWIN
MICRO-DEX
a We recommended using cutting fluid to improve tool life and accuracy of the machined surface.
a Indexable inserts and clamp screws are small and can easily be lost.
a If the insert screw is overtightened, the screw or wrench may be damaged.
Follow the guidelines shown below when tightening the clamp screw. The appropriate insert tightening torque is 0.5 (N/m).
Tightening of insert screw
Screw tightening without an insert
The main screw part may
be damaged if tightened.
z Hold the wrench flag as shown in the
diagram and turn it until finger tight.
Correct
°
z
x
90
x Hold the wrench flag and turn it
approximately 60° to 90°
(reference tightening angle).
Incorrect
°−
60
a Note that the procedures are performed starting with the insert screw on the back side when using a reverse holder.
Normal use
Reverse holder use
Insert easily falls out
Start with the insert clamp on the front side.
Start with the insert clamp on the back side.
a Use within recommended specification ranges.
Maximum L/d=5 (L : total length; d : shank diameter)
If the L/d ratio exceeds the recommended value, lower the cutting conditions.
y Repair
a If the holders break, Mitsubishi Materials can repair them.
MICRO-MINI TWIN
a When using a holder for general purpose / small automatic lathe.
Fig. 1
Internal face of the holder
a To avoid chipping of the 2nd cutting edge take care when inserting the boring bar into the holder.
Refer to fig.1. If the 2nd edge contacts the internal face of the holder there is a possibility that it
may chip.
s When using this type of holder, there is a possibility that damage to the shank and the 2nd cutting
edge can occur. Make sure that the clamping screws are tightened to the set torque value.
Additionally make sure that there is no clamping screw near the 2nd cutting edge as this can
break the boring bar.

e When using Mitsubishi holders
When using holders with a tool overhang of recommended quantity, ensure that the 3rd clamping
screw is removed prior to machining. The set torque value for clamping screw is 2.0 N•m.

a When using a square type holder:
a When installing the boring bar into the holder, tighten the clamp screws after ensuring the flats on
the tool holder are parallel to the reference flats on the micro-mini bar. Refer to fig.3.
s Make sure that the clamping screws are tightened to the recommended values.
d Do not tighten the clamp screw without a bar in place, otherwise the bridge will be deformed.
